Southern California's electricity system will be challenged this summer, and power emergencies may result if an extended drought leads to massive wildfires, the main U.S. electricity reliability watchdog said.

Southern California is the area that most concerns analysts at the North American Electric Reliability Corp (NERC), which issued its summer 2008 outlook recently.

Of Southern California, NERC said, "capacity margins will remain tight. Significant amounts of imported power are required to fortify capacity margins and preserve reliability, resulting in heavily loaded transmission lines into this area during peak conditions.

"As a result, unplanned major transmission or generation outages, or extreme temperatures/demand may lead to resource constraints."

NERC, of Princeton, New Jersey, is responsible for monitoring the reliability of the power grid in the United States, Canada and parts of Mexico.

NERC said voluntary conservation and on-call interruptible loads will likely be necessary more often than usual this summer.

As always, the biggest factor in how much demand will strain the power grids in California and the United States is the weather.

NERC said nationwide, U.S. temperatures were 12 percent warmer than normal in 2007 and 10 percent warmer than normal in 2006.

Last October, wildfires in San Diego County threatened a major transmission line and caused it to go off-line as the San Diego area nearly averted a power crisis, More wildfires could exacerbate an already precarious situation in California this summer, NERC said.

"Drought conditions persisting in Southern California, Nevada, eastern New Mexico and western Texas currently appear to have no impact on reliability, though potential for wildfires as a result of dry conditions can threaten infrastructure and will be monitored throughout the summer months," said the NERC study.

The California Independent System Operator, manager of the power grid on which flows 80 percent of the state's electricity, forecast a summertime peak demand of 49,071 megawatts, NERC noted.

The all-time peak demand in California was reached in July 2006 at 50,270 megawatts.

Cal ISO also saw a 1-in-10 chance that hot weather will increase that peak load forecast by 3,000 megawatts, thus reducing the capacity margin to less than 10 percent without additional power purchases.

Cal ISO spokeswoman Stephanie McCorkle said the grid manager agrees with the NERC assessment that the system needs to be under a careful watch this summer for Southern California. But she said it would take an unlikely confluence of events to create blackouts.

That would mean unexpectedly low imported power from outside California, high generation and/or transmission outages on a hot day, McCorkle said.

"We have more tools in our toolbox than we have had," said Cal ISO "We have more demand-response to tap now," said McCorkle, referring to customers that voluntarily cut use at times of high demand, often in turn for lower power rates.

In addition to high-use business customers, many residential customers have signed to have thermostats monitored remotely.

SaskPower eyes buying $300M worth of electricity from Flying Dust First Nation

SaskPower-Flying Dust flare gas power deal advances a 20 MW, 20-year Power Purchase Agreement, enabling grid supply from FNPA-backed generation, supporting renewable strategy, lower carbon footprint targets, and First Nation economic development in Saskatchewan.

 

Key Points

A 20 MW, 20-year PPA converting flare gas to grid power, with SaskPower buying from Flying Dust First Nation via FNPA.

✅ 20 MW of flare gas generation linked to Saskatchewan's grid

✅ 20-year term; about $300M total value to SaskPower

✅ FNPA-backed project; PPA targeted in 6-12 months

 

An agreement signed between SaskPower, which reported $205M income in 2019-20, and Flying Dust First Nation is an important step toward a plan that could see the utility buy $300 million worth of electricity from Flying Dust First Nation, according to Flying Dust's chief.

"There's still a lot of groundwork that needs to be done before we get building but you know we're a lot closer today with this signing," Jeremy Norman told reporters Friday.

Norman's community was assisted by the First Nations Power Authority (FNPA), a non-profit that helps First Nations get into the power sector, with examples like the James Bay project showing what Indigenous ownership can achieve.

The agreement signed Friday says SaskPower will explore the possibility of buying 20 megawatts of flare gas power from FNPA, which it will look to Flying Dust to produce.

20-year plan

The proposed deal would span 20 years and cost SaskPower around $300 million over those years, as the utility also explores geothermal power to meet 2030 targets.

The exact price would be determined once a price per metawatt is brought forward.

"We won't be able to do this ourselves," Norman said.

Flare gas power generation works by converting flares from the oil and gas sector into electricity. Under this plan, SaskPower would take the electricity provided by Flying Dust and plug it into the provincial power grid, complementing a recent move to buy more power from Manitoba Hydro to support system reliability.

"This is a great opportunity as we advance our renewable strategy, including progress on doubling renewables by 2030, and try to achieve a lower carbon footprint by 2030 and beyond," Marsh said.

Norman said the business deal presents an opportunity to raise money to reinvest into the First Nation for things like more youth programming.

For the next steps, both parties will need to sign a power purchase agreement that spells out the exact prices for the power generation.

Marsh expects to do so in the next six to 12 months, with development of the required infrastructure to take place after that.

US Approves Rule to Boost Renewable Transmission

FERC Transmission Rule accelerates grid modernization and interregional high-voltage lines, enabling renewable energy integration, load balancing, and reliability to advance net-zero goals while strengthening resilience, capacity expansion, and decarbonization across U.S. regional transmission organizations.

 

Key Points

A federal policy mandating interregional grid planning and cost sharing to expand high-voltage lines for renewables.

✅ Expands interregional high-voltage transmission capacity

✅ Improves reliability, resilience, and load balancing

✅ Aligns cost allocation and long-term planning for renewables

 

On May 13th, 2024, the US took a monumental step towards its clean energy goals. The Federal Energy Regulatory Commission (FERC) approved a long-awaited rule designed to significantly expand the transmission of renewable energy across the nation's power grid, a US grid overhaul that many advocates say was overdue. This decision aligns with President Biden's ambitious plan to achieve net-zero carbon emissions by 2050, with renewable energy playing a central role.

The new rule tackles a critical bottleneck hindering the widespread adoption of renewables – transmission infrastructure. Unlike traditional power plants like coal or natural gas that run constantly, solar and wind power generation fluctuates with weather conditions. This variability poses a challenge for the existing grid, which is not designed to efficiently handle large-scale integration of these intermittent sources, helping explain why the grid isn't 100% renewable today.

The FERC rule aims to address this by promoting the construction of new, high-voltage transmission lines, particularly those connecting different regions, where grid limitations in the Pacific Northwest have highlighted the need for better interregional transfers. This improved connectivity would allow for a more strategic distribution of renewable energy. Imagine solar energy harnessed in the sun-drenched Southwest being transmitted eastward to meet peak demand during hot summer days on the Atlantic Coast.

The benefits of this expanded transmission network are multifaceted. First, it unlocks the full potential of renewable resources by allowing for their efficient utilization across the country, a trend consistent with wind and solar surpassing coal in U.S. generation. Abundant wind power in the Midwest could be utilized on the West Coast, while surplus solar energy from the South could supplement demand in the Northeast.

Second, a more robust grid with a higher capacity for renewables reduces reliance on fossil fuel-based power plants and complements other ways to meet decarbonization goals across sectors. This translates to cleaner air and a significant reduction in greenhouse gas emissions, contributing to the fight against climate change.

Third, a modernized grid with improved long-distance transmission bolsters the nation's energy security. Extreme weather events, a growing concern due to climate change, can disrupt energy production in specific regions. This interconnected grid would provide a buffer, ensuring a more reliable and resilient power supply and helping put regions on the road to 100% renewables even during adverse weather conditions.

The FERC's decision is a win for environmental groups and the renewable energy industry. They see it as a critical step towards a cleaner energy future and a significant driver of job creation in the construction and maintenance of new transmission lines. However, concerns have been raised by some stakeholders, particularly investor-owned utilities. They worry about the potential cost burden associated with building these expansive new lines, and recent reports of stalled grid spending underscore those concerns and the need for efficient cost allocation mechanisms. Striking a balance between efficiency, affordability, and environmental responsibility will be crucial for the successful implementation of this policy.

Imported coal volumes up 17% during Apr-Oct as domestic supplies shrink

India Thermal Power Coal Imports surged 17.6% as CEA-monitored plants offset weaker CIL and SCCL supplies, driven by Saubhagya-led electricity demand, regional power deficits, and varied consumption across Uttar Pradesh, Bihar, Maharashtra, and Gujarat.

 

Key Points

Fuel volumes imported for Indian thermal plants, tracked by CEA, reflecting shifts in CIL/SCCL supply, demand, and regional power deficits.

✅ Imports up 17.6% as domestic CIL/SCCL deliveries lag targets

✅ Saubhagya-driven demand lifts generation in key beneficiary states

✅ Industrial slowdowns cut usage in Maharashtra, Tamil Nadu, Gujarat

 

The receipt of imported coal by thermal power plants, where plant load factors have risen, has shot up by 17.6 per cent during April-October. The coal import volumes refer to the power plants monitored by the Central Electricity Authority (CEA), and come amid moves to ration coal supplies as electricity demand surges, a power update report from CARE Ratings showed.

Imports escalated as domestic supplies by Coal India Ltd (CIL) and another state run producer- Singareni Collieries Company Ltd (SCCL) dipped in the period, after earlier shortages that have since eased in later months. Rate of supplies by the two coal companies to the CEA monitored power stations stood at 80.4 per cent, indicating a shortfall of 19.6 per cent against the allocated quantity.

According to the study by CARE Ratings, total coal supplied by CIL and SCCL to the power sector stood at 315.9 million tonnes (mt) during April-October as against 328.5 mt in the comparable period of last fiscal year.

The study noted that growth in power generation during the April-October 2019, with India now the third-largest electricity producer globally, was on account of higher demand from Pradhan Mantri Sahaj Bijli Har Ghar Yojana or Saubhagya Scheme beneficiary states. Providing connection to households in order to achieve 100% per cent electrification has in part helped the sector avert de-growth, as part of efforts to rewire Indian electricity and expand access.

Large states namely Uttar Pradesh, Bihar, Punjab, West Bengal and Rajasthan have recorded over five per cent growth in consumption of power. These states along with Odisha, Madhya Pradesh and Assam accounted for 75 per cent of the beneficiaries under the Saubhagya Scheme (Household Electrification Scheme). The ongoing economic downturn has led to a sharp fall in electricity demand from industrialised states. Maharashtra, which is also the largest power consuming state in India, recorded a decline in consumption of 5.6 per cent.

Other states namely Tamil Nadu, Telangana, Gujarat and Odisha too recorded fall in power consumed, echoing global dips in daily electricity demand seen later during the pandemic. These states house large clusters of mining, automobile, cement and other manufacturing industries, and a decline in these sectors led to fall in demand for power across these states. - The demand-supply gap or power deficit has remained at 0.6 per cent during the April-October 2019. North-East reported 4.8 per cent of power deficit followed by Northern Region at 1.3 per cent. Within Northern Region, Jammu & Kashmir and Uttar Pradesh accounted for 65 per cent and 30 per cent respectively of the regions power supply deficit.

How the dirtiest power station in western Europe switched to renewable energy

Drax Biomass Conversion accelerates renewable energy by replacing coal with wood pellets, sustainable forestry feedstock, and piloting carbon capture and storage, supporting the UK grid, emissions cuts, and a net-zero pathway.

 

Key Points

Drax Biomass Conversion is Drax's shift from coal to biomass with CCS pilots to cut emissions and aid UK's net-zero.

✅ Coal units converted to biomass wood pellets

✅ Sourced from sustainable forestry residues

✅ CCS pilots target lifecycle emissions cuts

 

A power station that used to be the biggest polluter in western Europe has made a near-complete switch to renewable energy, mirroring broader shifts as Denmark's largest energy company plans to end coal by 2023.

The Drax Power Station in Yorkshire, England, used to spew out millions of tons of carbon dioxide a year by burning coal. But over the past eight years, it has overhauled its operations by converting four of its six coal-fired units to biomass. The plant's owners say it now generates 15% of the country's renewable power, as Britain recently went a full week without coal power for the first time.

The change means that just 6% of the utility's power now comes from coal, as the wider UK coal share hits record lows across the national electricity system. The ultimate goal is to stop using coal altogether.

"We've probably reduced our emissions more than any other utility in the world by transforming the way we generate power," Will Gardner, CEO of the Drax Group, told CNN Business.

Subsidies have helped finance the switch to biomass, which consists of plant and agricultural matter and is viewed as a promising substitute for coal, and utilities such as Nova Scotia Power are also increasing biomass use. Last year, Drax received £789 million ($1 billion) in government support.

 

Is biomass good for the environment?

While scientists disagree over the extent to which biomass as a fuel is environmentally friendly, and some environmentalists urge reducing biomass use amid concerns about lifecycle emissions, Drax highlights that its supplies come from from sustainably managed and growing forests.

Most of the biomass used by Drax consists of low-grade wood, sawmill residue and trees with little commercial value from the United States. The material is compressed into sawdust pellets.

Gardner says that by purchasing bits of wood not used for construction or furniture, Drax makes it more financially viable for forests to be replanted. And planting new trees helps offset biomass emissions.

Forests "absorb carbon as they're growing, once they reach maturity, they stop absorbing carbon," said Raphael Slade, a senior research fellow at Imperial College London.

But John Sterman, a professor at MIT's Sloan School of Management, says that in the short term burning wood pellets adds more carbon to the atmosphere than burning coal.

That carbon can be absorbed by new trees, but Sterman says the process can take decades.

"If you're looking at five years, [biomass is] not very good ... If you're looking at a century-long time scale, which is the sort of time scale that many foresters plan, then [biomass] can be a lot more beneficial," says Slade.

 

Carbon capture

Enter carbon capture and storage technology, which seeks to prevent CO2 emissions from entering the atmosphere and has been touted as a possible solution to the climate crisis.

Drax, for example, is developing a system to capture the carbon it produces from burning biomass. But that could be 10 years away.

 

The Coal King is racing to avoid bankruptcy

The power station is currently capturing just 1 metric ton of CO2 emissions per day. Gardner says it hopes to increase this to 10,000 metric tons per day by the mid to late 2020s.

"The technology works but scaling it up and rolling it out, and financing it, are going to be significant challenges," says Slade.

The Intergovernmental Panel on Climate Change shares this view. The group said in a 2018 report that while the potential for CO2 capture and storage was considerable, its importance in the fight against climate change would depend on financial incentives for deployment, and whether the risks of storage could be successfully managed. These include a potential CO2 pipeline break.

In the United Kingdom, the government believes that carbon capture and storage will be crucial to reaching its goal of achieving net-zero greenhouse gas emissions by 2050, even as low-carbon generation stalled in 2019 according to industry analysis.

It has committed to consulting on a market-based industrial carbon capture framework and in June awarded £26 million ($33 million) in funding for nine carbon capture, usage and storage projects, amid record coal-free generation on the British grid.

UK electricity and gas networks making ‘unjustified’ profits

UK Energy Network Profits are under scrutiny as Ofgem price controls, Citizens Advice claims, and National Grid margins spark debate over monopolies, allowed returns, consumer bills, rebates, and future investment under tougher regulation.

 

Key Points

UK Energy Network Profits are returns set by Ofgem for regulated grid operators, shaping consumer bills and investment

✅ Ofgem sets allowed returns for monopoly networks via price controls

✅ Dispute over interest rates, bond yields, and risk premiums

✅ Reforms proposed: shorter controls, tougher investor incentives

 

Companies that run Britain’s electricity and gas networks, including National Grid, are making “eye-watering” profits at the expense of households, according to a well-known consumer group.

Citizens Advice believes £7.5bn in “unjustified” profits should be returned to consumers who pay for network costs via their electricity and gas bills, with parallels seen in a deferred BC Hydro costs report abroad, although its figures have been contested by the energy industry and regulator.

Ownership of electricity and gas networks came under the spotlight in the run-up to June’s general election, after the Labour party said in its manifesto it would bring both national and regional grid infrastructure to back into public ownership, amid wider debates about grid privatization concerns elsewhere, over time.

Electricity sector privatisation began in 1990 and the gas industry was privatised in 1986. Energy network companies — which own and operate the cables and wires that help deliver electricity and gas to homes and businesses — are in effect monopolies that are regulated by Ofgem. Ofgem evaluates what their costs, including the cost of capital to finance investments, might be over an eight-year “price control” period, similar to determinations like the OEB decision on Hydro One rates in Ontario, Canada. Citizens Advice claims many of the regulator’s calculations for the most recent price control went “considerably in networks’ financial favour”.

It believes assumptions Ofgem made about factors such as the future path of interest rates and returns on government bonds were too generous, with international contrasts like power theft challenges in India illustrating different risk contexts, as was the regulator’s assessment of the risk associated with operating a network company. 

These “generous” assumptions will lead to network companies making average profit margins of 19 per cent and an average return of 10 per cent for their investors at the expense of consumers, Citizens Advice claims in a report published on Wednesday, which recommends a shorter price control period to allow for more accurate forecasting.

“Decisions made by Ofgem have allowed gas and electricity network companies to make sky-high profits that we’ve found are not justified by their performance,” said Gillian Guy, chief executive of Citizens Advice. Ofgem defended its regulatory regime, saying it helped to cut costs, improve reliability and customer satisfaction. 

“Ofgem has already cut costs to consumers by 6 per cent in the current price control and secured a rebate of over £4.5bn from network companies and is engaging with the industry to deliver further savings, with some regions seeing Ontario electricity rate reductions for businesses as well,” said Dermot Nolan, chief executive of the energy regulator.

Mr Nolan insisted the next price controls would be “tougher for investors”. The current price controls for the gas and electricity transmission networks, plus gas distribution, run until 2021 and until 2023 for local electricity distribution networks.

“While we don’t agree with its modelling and the figures it has produced, the Citizens Advice report raises some important issues about network regulation which will be addressed in the next control,” Mr Nolan said.

The Energy Networks Association, a trade body, refuted the claims of Citizens Advice, insisting that costs had fallen by 17 per cent in real terms since privatisation. The current regulatory framework was established after a public consultation, it said, adding that today’s report repeated several old claims that had previously been rejected by the Competition and Markets Authority.

“Our energy networks are among the most reliable and lowest cost in the world and their performance has never been better. In the next six years energy network companies are forecasted to deliver £45bn of investment in the UK economy,” a spokesman for the networks association added. National Grid said that since 2013 it had generated savings of £460m for bill payers.

Power firms win UK subsidies for new Channel cables project

UK Electricity Interconnectors secure capacity market subsidies, supporting winter reliability with seabed cables to France and Belgium via the Channel Tunnel, lowering consumer costs, squeezing coal, and challenging new gas plants through cross-border energy trading.

 

Key Points

High-voltage cables linking Britain to Europe, securing backup capacity, cutting costs and boosting winter reliability.

✅ Won capacity market contracts at record-low prices

✅ Cables to France and Belgium via Channel Tunnel, seabed routes

✅ Squeezes coal, challenges new gas; renewables may join market

 

New electricity cables across the Channel to France and Belgium will be a key part of keeping Britain’s lights on during winter amid record electricity prices across Europe in the early 2020s, after their owners won backup power subsidies in a government auction this week.

For the first time, interconnector operators successfully bid for a slice of hundreds of millions’ worth of contracts in the capacity market. That will help cut costs for consumers, given how electricity is priced in Europe today, and squeeze out old coal power plants.

Three new interconnectors are currently being built to Europe, almost doubling existing capacity, with one along the Channel Tunnel and two on the seabed: one between Kent and Zeebrugge and one from Hampshire to Normandy. 

The interconnectors were success stories in this week’s capacity auction, which saw power firms bid to provide backup electricity in the winter of 2021/22. Prices for the four-year contracts hit a record low of £8.40 per kilowatt per year, which analysts described as a shock and well below expectations.

One industry source said the figure was “miles away” from what is needed to encourage companies to build big new gas power stations, which some argue are necessary to fill the gap when the UK’s ageing nuclear reactors close as Europe loses nuclear power across the region over the next decade.

While bad news for those firms, the low price is good for consumers. The subsidies will add about £525m to energy bills, or £5.68 for the average household, compared with £11 for the year before, according to analysts Cornwall Insight.

Existing gas power stations scooped up most of the contracts, but new gas ones lost out, as did several coal plants. Battery storage plants, a standout success in the last auction, fared comparatively poorly after changes to the rules.

Experts at Bernstein bank said the the misses by coal meant that around half the UK’s remaining coal power capacity could close from October 2019, when existing capacity market contracts run out. Chaitanya Kumar, policy adviser at thinktank Green Alliance, said: “Coal’s exit from the UK’s energy system just moved a step closer as coal contracts fell by half compared with last year.”

Tom Edwards, an analyst at Cornwall Insight, said that more interconnectors were likely to bid into future rounds of the capacity market, such as the cable being laid between Norway and the UK. Relying on foreign power supplies was fine, he said, provided Brexit did not make energy trading more difficult and the interconnectors delivered at times of need, where events like Irish grid price spikes illustrate the stress points.

However, one industry source, who wants to see new gas plants built in the UK, said the results showed that the system was not working, amid UK peak power prices that have climbed in recent trading. “That self-sufficiency doesn’t seem to be a priority at a time when we’re breaking away from Europe is a bit weird,” they said.

But the prospects for new gas plants in future rounds of the capacity market look bleak. They will very likely face a new source of competition next year, if energy regulator Ofgem approves a proposal to allow renewables to compete too.
